SUPPORT FORELECTRIC-LAMP SOCKETS.

Speciilcation of Letters Patent.

Application lled January 16, 1913. Serial No. 742,399.

T0 all whom it may concern:

Be it known that- I, JACOB As SMITH, a citizen of the United States, residing at Chica-go, in the count)T of Cook and yStat/e of Illinois, have invented a cer ainnew and useful Improvement in Suppo ts for Electric-Lamp Sockets, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this speciication.

My invention relates. to an improved lamp 'socket support for electric lamps, by means of which an electric lamp may be .temporarily held and supported in any desired position and readily moved from one place to another and further that it may be attached or supported from different objects, such as shelves, table tops, etc., by means of a special form of spring clamp 'connected with the socket support. The several drawings illustrating my in- ,vention are as follows:

Figure l shows the socket support and clamp in perspective view lsupportlng a lamp socket from .n shelf. F ig. 2 is a top View of the socket supporting portion of the device.

l Similar numerals refer t-o similar parts throughout the several views.

As shown inthe drawings the' device consists 0f a socket clamp comprising a ringshaped band 1, of spring metal open at one side. The band 1 is secured by a strip of similar material 2, to the convolutions 3,01 a, spring 4, formed of cylindrical wire or rod of spring material of suitable diameter. The convolutions 3 are so disposed relatively to the member 2, that one convolution is upon one side of said member While two other convolutions are uponthe opposite side of said member, thus securely h'olding the member l2 in place upon the spring 4, and therefore securely supporting the socket clamp 1 therefrom as well as socket 5 and lamp 6 when the latter is in position inthe socket. The spring band 1 and the member 2 may be secured together in any desired manner, as-for example by rivets 7 as indicated. The ,ends of the clamp 4 opposite to the Iconvolutions 3, are bent, as

vshown at 8 and 9'soas`to lie adjacent `to each other and project lin opposite directions, and are extended suicientlyso Athat the rings 10 and 1l formed in substantially parallel planes approximately at right angles to the portions 8 and 9, are normally moved toward each otherlby the spring of the clamp 4 and particularly b the spring of the convolutions 3 of said, c amp. As a result the main members of the clamp 4 between the portions 8 and 9 and the convolutions 3 may be engaged and grasped by the handso that the pressure exerted upon these main members will force the rings 10 and l1 away from each other so that they may be placed upon opposite sides of the particular article or thing to which it is desired to secure the electric lamp. In Fig. 1 of the drawings this article is assumed to be a shelf 12, the ring l1 being disposed above and the ring l() below said shelf, and the spring of the clamp 4, holds these rings in engagement with the top and bottom of the. shelf with sufficient force so that the lamp socket and lamp are securely held in the desired position. When it is desired to` remove the lamp from the shelit` 12 all that is necessary is to press the main members of the clamp 4, toward each other,thus free-4 ing the rinus 10 and 11 from the shelf, for which condition the clamp and socketv support together with the socket and lamp may .readily be removed.

ysurfaces when said surfaces are engaged to support the lamp and socket.

It will at once appear that the socket support above described may be attached to any object or article whether :dat or round which can be inserted 'between the rings 10 and 11 when the latter are separatedA from each other as described above.

'While I have shown my invention in the particular embodiment described above it will be understood that I do not limit myself to this exact construction, but on the other hand may employ other parts constructed and operating in substantially the same Way for accomplishing the results contemplated.

l 1. In a support for an electrlo lamp socket,

the combination of a sup ort for the socket, -a member secured to sai support, a spring clamp having a plurality of convolutions formed at one end upon opposite sides of said memberl to secure, it to said clamp, said clamp consisting of a bent cylindrical wire or rod of spring materialthe ends of which are conformed into opposite clamping surfaces tending to move into engagement with each other by the spnring of the clamp and disposed so that they may be moved from each other by pressure exerted upon the clamp. v

2. Ina support for an electric lamp socket, the combination of a clamping device of spring material having its ends conformed into. opposition clamping portions, a plurality of convolutions formed in its middle portion, said convolutions and said clamping portions being connected by main members of the spring clamp, said main members so disposed that pressure upon them will move they said clampingpportions away from each other, and a socket support engaging the outer portions of the convolutions.

3. In a support for an electric lamp socket, the combination of a clamping device of spring material having its ends conformed into opposite clamping portions,a plurality of convolutions formed in its middle portion, said convolutions and said clamping t portions being connected by main members of the spring clamp; said main members so disposed that pressure upon them will move the said clampin portions away from each other, and a soc et support secured to the convolutions at a point farthest from the clamping portions. p

4. In a support for an electric lamp socket, the combination of* a clamping device of spring material having yopposite clamping portions formed upon its ends, the central portion of said clamping device being formed into a spring portiontending to hold said clamping device in clamping position,- said device also having mainmembers con- 5. In a support for an electric lamp socket,

the combination of a clampingl device of spring material having opposite clamping portions formed upon its ends, the central portionof said clamping device being formed into a spring portion tending to hold said clamping device in clamping position, said device also having; main members connect-4 ing said spring portion with said clamping A portions and so disposed that pressure upon them will move said clamping portions away from each other against the tendency of said spring portion, a socket support 'carried by said spring portion, and olf-sets in said clamping portions extending outwardly therefrom to engage a rod between them.

.6. In a support for an electric lamp socket, the combination of a clam ing device of spring wire bent at substantially itsmiddle portion to form a spring and h avlng oppositely disposed clamping portions formed upon its ends, said wire being formed into main members connecting said clamping portions with said spring portionand so disposed that pressure upon said main members will move said clamping portions away from each other against the tendency of said spring portion, a socket support carried by said, clamping device and off-sets in said clamping portions extending outwardly therefrom to receive between them a rod, the

inner surfaces of said oE-sets being lprovided with teeth to grip said rod.

In witness whereof, scribed my name this 14th day of January,
